1.Assume that the seek time is 8 ms, the rotational delay is 4 ms, the latency time is 4 ms, and the transfer time is 3 ms. The total disk access time is _________ millisecond

2.Have a scratchpad, pencil, and calculator on you to work on this question. A hard disk is rotating at 11,400 revolutions per minute (rpm). Each track is divided into 2000 sectors. The transfer time of 800 sectors from this disk to memory is approximately ______ milliseconds [ms].
